hi
how can we create in cmfb amplifier circuit a CM voltage?
explenation that CM voltage is ideal( or desired) common mode output voltage.
i am reading Gray & Mayer book and in chapter 12 (about cmfb) has been used CM voltage , but in this chapter does not have explained how to create this voltage
i think with an inverter that its output tied to its input ,maybe can be create desired voltage but the mismatch and thermal effect will change this value.
thanks
